We Keep Coding

To make certain JS code more important than another (disappear on mouse out)

I know this might be silly but I would like to know if there is a way to realize.
Basically, I would like the dropdown-content element to 'KEEP DISPLAYING' even after 3 secs of mouse moving-out of the parental 'dropbtn' button or element.
E.g. code:
$(function() {
$('#dropbtn').hover(function() {
$('.dropdown-content').css('display', 'block');
}, function() {
// on mouseout:
setTimeout(function(){$('.dropdown-content').css('display', 'none');}, 3000);
});
$('.dropdown-content').hover(function(){
$('.dropdown-content').css('display', 'block');
},function(){
$('.dropdown-content').css('display', 'none');
})
});
Current issue is that setTimeout() function is overriding my desired way on this particular line of JS code:
$('.dropdown-content').css('display', 'block');
In another word, I want setTimeout() to be effective if and only if I set not my mouse cursor on 'dropdown-content' div.
Hope someone can help out :)

Instead of using hover, you could use mouseenter/mouseleave to 'toggle' the .dropdown-content, except the delay of 3s on mouseleave:
$(function() {
var dropdownTimeout = null;
$('#dropbtn').mouseenter(function() {
if(dropdownTimeout) {
clearTimeout(dropdownTimeout);
dropdownTimeout = null;
}
$('.dropdown-content').css('display', 'block');
});
$('#dropbtn').mouseleave(function() {
dropdownTimeout = setTimeout(function(){$('.dropdown-content').css('display', 'none');}, 3000);
});
});

How to clear setTimeout on jQuery mouseover #id

This is my current code to run the series of setTimeout functions. How do I stop these when either the mouse moves, or is over a certain element?
$( document ).ready(function() {
clicky()
function clicky() {
setTimeout(function () {jQuery('#1500').trigger('click');}, 3000);
setTimeout(function () {jQuery('#1990').trigger('click');}, 6000);
setTimeout(function () {jQuery('#2010').trigger('click');}, 9000);
setTimeout(function () {jQuery('#battle').trigger('click');}, 12000);
setTimeout(function () {
jQuery('#water').trigger('click');clicky()
}, 15000);
}
});

You essentially need to save a reference to your timeouts so that they can be cleared when you need them to be. In the following example, I just used an object so that you could specify which timeout you wanted to affect, if desired.
Here's a working fiddle that will clear the timeouts on hover, then reset them when the mouse leaves: http://jsfiddle.net/6tQ4M/2/
And the code:
$(function(){
var timeouts = {};
function setTimeouts () {
timeouts['#1500'] = specifyTimeout('#1500', 3000);
timeouts['#1990'] = specifyTimeout('#1990', 6000);
timeouts['#2010'] = specifyTimeout('#2010', 9000);
timeouts['#battle'] = specifyTimeout('#battle', 12000);
timeouts['#water'] = specifyTimeout('#water', 15000, function(){
console.log('reset the timeouts');
clearTimeouts();
setTimeouts();
});
}
function clearTimeouts () {
for(var key in timeouts){
if(timeouts.hasOwnProperty(key)){
clearTimeout(timeouts[key]);
delete timeouts[key];
}
}
}
function specifyTimeout (id, time, callback) {
return setTimeout(function(){
$(id).trigger('click');
if(callback){
callback();
}
}, time);
}
$('a').on('click', function(){
$('#projects').append('clicky clicky!');
});
$('#map').on('mouseover', clearTimeouts);
$('#map').on('mouseleave', setTimeouts);
setTimeouts();
});
Let me know if you have any questions about the code at all!

Your setTimeout needs to be defined to a variable, so that it can be cleared by passing to clearTimeout(). Something like:
var interval = setTimeout(function() {
//msc
}, 8000);
window.clearTimeout(interval);

Well, according to what you ordered, when you hover an area, the setTimeOut should be fired, and when you are out of this region, the setTimeOut should be reset.
This is the code:
HTML
<div id="map"></div>
CSS
#map{
width:100px;
height:100px;
background-color: black;
}
Javascript
var timeoutHandle;
$('#map').mouseover(function(event){
window.clearTimeout(timeoutHandle);
});
$('#map').mouseout(function(event){
timeoutHandle = window.setTimeout(function(){ alert("Hello alert!"); }, 2000);
});
Basically you should keep a reference to the setTimeOut, in this case the variable is timeoutHandle, call clearTimeOut on mouse over and call setTimeOut again to reset the timer.
Here is the jsFiddle:

The same principle can be used for more than one setTimeOut timer.

How to detect whether mouseout is true or not?

I have this simple fiddle as a working example-
Jsfiddle
I am trying to detect mouseout event from a div section.
When i mouseover on this image it shows caption; saying "Change Image". After 5 seconds caption goes fadeOut.
I am using setInterval to set it accordingly. Now if I do mouseout of this image, then only I want Interval function should be called.
How do i detect mouseout event in jQuery?
Tried-
$(function () {
$('.image-profile').mouseover(function () {
$('.change-image').stop().show();
if ($('.image-profile').mouseout()== true) {
TimeOut();
}
});
setInterval(function TimeOut() {
$('.change-image').fadeOut()
}, 5000
);
});

var ImageProfileTimer;
$('.image-profile').on('mouseenter',function(){
clearTimeout(ImageProfileTimer);
$('.change-image').stop().show();
}).on('mouseleave',function(){
ImageProfileTimer = setTimeout(function(){
$('.change-image').fadeOut()
}, 5000);
});
Use setTimeout and clearTimeout
Demo : http://jsfiddle.net/xMNTB/9/

$('.image-profile').on('mouseleave', function() {
setTimeout(function() {
$('.change-image').fadeOut()
}, 5000);
});

http://jsfiddle.net/xMNTB/7/
Now the div show up on mouse enter and disappears 5 seconds after mouse leave.
$(function () {
$('.image-profile').mouseenter(function () {
$('.change-image').stop().show();
});
$('.image-profile').mouseleave(function () {
setTimeout(function TimeOut() {
$('.change-image').fadeOut()
}, 5000);
});
});

Try This:
(function () {
$('.image-profile').mouseover(function () {
$('.change-image').stop().show();
if ($('.image-profile').mouseout() == true) {
TimeOut();
}
}).mouseout(function () {
setInterval(function TimeOut() {
$('.change-image').fadeOut()
}, 5000);
});
});

How to change few css class on button in jQuery by timer?

When document is ready, there is a button that gets a new class names frame1. I want to set another class on this button after two seconds.
$(document).ready(function () {
setTimeout(function () {
$('#button').addClass('frame1')
}, 2000);
});
I want to add another class 'frame2' after two seconds if that is possible?

If you just want to add a class every coule of seconds until you have no more classes to add, you could use an interval and then clear it when the classes have all been added:
var group = [ 'whiteFG', 'redBG' ];
var intvl= setInterval(function(){
group.length
? $("#foo").addClass(group.pop())
: clearInterval(intvl) ;
}, 2000);
Fiddle: http://jsfiddle.net/EvXPy/
Or you could simply iterate over your array of class names and set timeouts from there:
$(['redBG','whiteFG']).each(function(i,o){
setTimeout(function(){
$("#foo").addClass(o);
}, i * 2000 );
});​​​​​​​​
Note that the first effect will run immediately since i is equal to the index of 0, meaning the timeout happens instantly. If you want this to be delayed, you can increment i as you see fit before multiplying by 2000.
Fiddle: http://jsfiddle.net/EvXPy/1/

You can do it this way.
$(document).ready(function () {
setTimeout(frame1(), 2000);
});
function frame1() {
$('#button').addClass('frame1');
setTimeout(frame2(), 2000);
}
function frame2() {
$('#button').addClass('frame2');
}
Or you could do it this way.
$(document).ready(function () {
setTimeout(function () {
$('#button').addClass('frame1')
}, 2000);
setTimeout(function () {
$('#button').addClass('frame2')
}, 4000);
});

setTimeout(function () {
$('#button').addClass('frame1');
}, 2000);
setTimeout(function () {
$('#button').addClass('frame2');
}, 2000);
UPDATE:
If you want to check whether class is exists then do this way.
setTimeout(function () {
$('#button').addClass('frame1');
if($('#button').hasClass('frame1')) {
setTimeout(function () {
$('#button').removeClass('frame1').addClass('frame2');
}, 2000);
}
}, 2000);

Issues with clearTimeout

I am trying to build a simple navigation with sub-navigation drop-downs. The desired functionality is for the drop-down to hide itself after a certain amount of seconds if it has not been entered by the mouse. Though if it is currently hovered, I would like to clearTimeout so that it does not hide while the mouse is inside of it.
function hideNav() {
$('.subnav').hover(function(){
clearTimeout(t);
}, function() {
$(this).hide();
});
}
$('#nav li').mouseover(function() {
t = setTimeout(function() { $('.active').hide()}, 4000);
//var liTarget = $(this).attr('id');
$('.active').hide();
$('.subnav', this).show().addClass('active');
navTimer;
hideNav();
});
What am I missing? Am I passing the handle wrong?

You should also clear the timeout in mouseover, before setting the new timeout.
Otherwise a timeout started before will still be active, but no longer accessible via the t-variable.

you can make the timer variable global.
function hideNav() {
$('.subnav').hover(function(){
clearTimeout(window.t);
}
}
$('#nav li').mouseover(function() {
window.t = setTimeout(function() { $('.active').hide()}, 4000);
});

Try doing it the recommended way (JS statement as a string):
t = setTimeout("$('.active').hide()", 4000);
